EDMONTON, Alberta (AP) Erik Karlsson's two-game suspension didn't slow him down one bit.
Karlsson had been banned for an illegal check to the head of Kings forward Austin Wagner.
''It's never fun to be out of the lineup especially for the reason that I was out for - it was a little unjustified I think,'' Karlsson said. ''But I made the most of it and I watched the games and sometimes it's good to watch the game from afar, too, you figure a few things out. I was excited to get back today and do everything I could to stay in it and luckily it was only two (games).''
Joonas Donskoi and Tomas Hertl also scored for the Sharks, who have won two in a row.
Connor McDavid had two goals and Caleb Jones and Leon Draisaitl also scored for the Oilers, who have lost a season-high five straight.
''They won the one-on-ones, they knocked us out of the box, they won the net front. They owned us,'' Oilers coach Ken Hitchcock said.
McDavid got Edmonton on the board 6 1/2 minutes in, but Donskoi scored 17 seconds later. That was the first of six straight San Jose goals.
Hertl put the Sharks ahead with a spin move before beating goalie Cam Talbot for his 14th of the season. Couture buried a one-timer in the second period, and Erik Karlsson scored on a long screen shot.
''You can see his impact on our team with the players around him,'' DeBoer said of Erik Karlsson. ''You take him for granted a little bit, you realize when you take him out the hole is there and I think every week he's getting more comfortable here.''
In the third, Melker Karlsson redirected Brent Burns' point shot and Couture beat Talbot to a loose puck to make it 6-1.
Edmonton responded a couple minutes later when Jones recorded his first career goal.
''I'm sure in a couple of days when I look back on it, I will have a little smile,'' said the rookie defenseman, younger brother of Seth Jones of the Columbus Blue Jackets. ''But there was a lot of bad things tonight in our game. The moment I scored it, it just felt like a garbage-time goal.''
NOTES: Oilers F Jujhar Khaira returned to the lineup following a two-game suspension for an illegal cross-check.
Sharks: Play at Calgary on Monday night.
Oilers: Host Winnipeg on Monday night.
